APPARATUS FOR MEASURING CURRENT OF VEHICLE BATTERY AND RESISTANCE MEMBER FOR MEASURING CURRENT OF VEHICLE BATTERY

摘要

PURPOSE: A current measurement apparatus of a vehicle battery of various ranges and a resistor unit for current measurement are provided to measure a current value of various ranges flowing in a battery of a vehicle accurately. CONSTITUTION: A current measurement apparatus of a vehicle battery includes a ground terminal of a vehicle, a battery and a resistor unit. The resistor unit is arranged between the ground terminal and a cathode of the battery, and connects the ground terminal and the cathode of the battery serially. Cross-sectional area of the resistor unit becomes gradually smaller as going from a part connected to one of the ground terminal and the cathode of the battery to a part connected to another one.
